Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568934, here are decompositions:

13 + 31568921 = 31568934
17 + 31568917 = 31568934
37 + 31568897 = 31568934
83 + 31568851 = 31568934
101 + 31568833 = 31568934
107 + 31568827 = 31568934
167 + 31568767 = 31568934
191 + 31568743 = 31568934

Showing the first eight; more decompositions exist.
